Not as such, just fanatics like me posting information:
Celestian - Jedi, healing etc. Operates off keywords similar to AoW3 Theocrat (e.g. “devout”)
Psynumbra - Sith, break your mind. Apparently their T4 requires population, and is a beast.
Xenoplague - genetic experimentation gone wrong, virus infecting things. Apparently how this works is you research the Xenoplague unit, and then enemies you kill have a chance to spawn one of those researched units, which in turn may evolve into a higher level unit. Basically, “free” units (no energy used, no city production or time) but you have to invest into it.
Promethean - purifiers. Kill it with fire. Ostensibly created to cleanse Xenoplague infected worlds. End up cleansing whatever needs cleansing. Imho their Walkers are the coolest unit we’ve yet seen.
Voidtech - Bend the laws of time and space. Some cool looking stuff here, including battlefield black holes of some sort, and a unit that can duplicate itself, the duplicate having the same abilities (so you duplicate the unit can double grenade stuff) Seems centred on inflicting dimensional instability on enemies, which are stacking debuffs, so lvl 1 gives x weakness, lvl 2 some other weakness etc
Synthesis - the matrix/singularity, under your control. Apparently the nearest there is to a hard counter for anything, because this tech can really mess with machines (in other words, almost hard counters machine heavy units, and therefore machine heavy races like Dvar and Vanguard, but has very little bring against organics. Also, you can network your units, which is uploading them to your version of the internet, gives some buffs.
Edit: The races:
Vanguard - closest to vanilla. Flexible, don’t excel at anything, no real weaknesses. This is the Star Union military, but they’ve been in cyrosleep for 200 years.
Dvar - space Dwarves. Their scout can prospect a sector, which extracts resources (free resources!!!) The race has a strong heavy metal vibe.
Kir’ko - used to be a hive race, but the Hive Queen got lobotomised by the Star Union, because they (the Union) was looking for a hallucinogenic drug that said Queen produced. So, this race is “broken” and looking to either get revenge, or just rebuild.
Amazons - all female (not explained why) descendants of scientists isolated after the Star Union collapsed, that learned to terraform and genetically modify plants and animals, which they then ride. Think Avatar meets Predator meets MMA fighters, who use bows…
Syndicate - unfairly represented hard working Merchants who have been slandered as slavers. Indentured servitude has lots of benefits don’t you know? Think Baron/House Harkonnen from Dune.
Assembly - Cyborgs apparently. Not yet revealed officially:
